IMPROVEMENT IN HORSESHOE-CALKING VISES.

Specification forming part of Letters Patent N0. 53,733, dated April 3, 1866.

To all whom it may concern.'

Be it known that I, WILLIAM DELANo, of Bangor, in the county of Penobscot and State of Maine, have invented a new and useful Horseshoe-Oalking Vise and I do hereby declare the same to be fully described in the following specication, and represented in the accompanying drawings, of which- Figure l is a top view, Fig.2 a side elevation, Fig. 3 a front view, and Fig. 4 a longitudinal section, of it.

The nature of my invention consists in the combination and arrangement ot' a vibratory iaw-plate and a common vise having two jaws, such jaw-plate being placed between the said jaws and so as to be used in manner and for the purpose as hereinafter set forth.

In the drawings, A is the stationary, and B the movable,ja\v of a vise. The shank b or the movableja-w, at its foot, turns on a pin, c, extending from one to the other of the two plates d d projecting from the shank a of the stationary jaw A. A bolt, G, passing through the shank of the stationary jaw also goes through a slot, c', in the shank b, and isjointed to a cammed lever, D, which is connected with a i'oottreadle, E, by means ot a rod,f, jointed to the two. By pressing the treadle downward thejaw B will be caused to move toward the jaw A, and by relieving the treadle from such downward pressure a spring, F, fixed to the shank a and bearing against the shank b,will cause thejaw B to move away from thejaw A.

Between the two jaws A B is the vibrating jaw-plate G, which, at its lower end, is supported by, and so as to be capable ot' turning on, a pin, g, going through it and into the plates d d, the `jaw-plate G being thus free to move toward and against either of the graspingfaces of thejaws AB. The upper edge of the jaw-plate G is rounded or curved to or about to the curve of a horseshoe at its toe. The purpose of the said jaw-plate so applied to a vise is to support the back part of a shoe duringthe formation of a toe-calk or a heel-call; by hammering the metal for the calk down upon one ot' the jaws, and also to enable the shoe, while either calk is being made on so hammered down, to be held by tongs in the left hand ofthe blacksmith.

In accomplishing the formation oi' the toecalks by the aid of a vise having two jaws only, and one ot' them extending above the other, the smith can easily hold the shoe by tongs in his left hand while he is hammering down the right calk; but when he has to hold the shoe for the formation ot' the left calk it would be necessary to shift the tongs into his right hand and hold and work the hammer with the left handa matter both awkward and inconvenient in its performance. With the movable or vibratory plate or bearer G, to extend between and above thejaws in manner as represented, the shoe, during the formation of each calk, may be sustained by tongs held in the left hand of the smith, whose right hand will be free to wield the hammer, for after forming one heel-calk against onejaw, and with the shoe griped between the said jaw and the vibratory plate resting against the other jaw, he has only to X the shoe between the plate and the latterjaw in order to enable him to hammer down the other calk.

WVhat, therefore, I claim as my invention rllhe new orimproved horseshoe-calkng vise made substantially as described, viz: ot' the vibratory bearer or plate G and the common vise having two jaws, -A B, the whole being arranged and combined substantially in manner and so as to operate as and for the purpose specified.

VILLIAM DELANO.
